- To all whom, it may concern:

' Be it known that I, WILLIAM EMIL BOGK, a citizen of the United States,residing at T- ledo, inthecounty of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Machines for MakingHollow Glass Articles, of which the following is a e accompanyingdrawings.

10.:- v The invention relates to machines for making hollow glassarticles; and it consists in a machine in which the glass may begathered in the usual way and delivered to a blank-,

mold and in which the blank formed by ,oo'm'pressed air applied to theinner end there- 1'0! and thenis onned into a hollow blank by blowing itin a blank-mold, the blank bethen-transferred to a blowing mold, where.it s blown to itscompleteform; so 1. jflheinvention further consists nthe con- 7 struction, arrangement, and combination of.

are various parts, .as' more fully hereinafter described,and-particularly pointed out in .the claims. "asv chine. from theopposite side.

Figure 1 is a. side elevation of the ma- Fig. 2 is a similar elevationlooking 7 Fig. .3 is a vertical central section through the machine andthrough the blank and blowing molds there'- of, showing some of theparts. in elevation to more clearly illustrate the same. Fig. ,4 is aperspective view of the body-blank mold in its open osition; and Fig. isa perspec- ;tive view 0? the neck-mold or the lower portion of theblank-mold, showing it also in the open position.

Ais a suitable frame upon which the operatin arts are supported,preferably having .a ta e B at the top. The blank-mold 1 form,preferably, of the body portion C, (shown in Fig. 4,) made two sections,hinged together on the pivot-pin D in the usual way of making molds; Thesections are provided with. the operating-handles a,

to, these levers being pivoted together at F and normally held in theclosed position bys ring it encircling the rod'and hearing at' t e lowerend against the bracket 0 and at its upper end against the. lever 11,supported in the bracket 7' on'the head G. This lever is forked toembrace the plunger-rod d and is connected therewith by means-of pinsis, en-

tering slots Z in the lever.

The head e is shapedto fit the upper end of {he body-blank mold C. It isprovided wit 1' an air-passage m, which is connected with an air-pipe nfor supplying compressed air to the interior of the blank-mold, as willbe hereinafter described. This pipe n is con trolled by a suitableshut-oil valve 0 and leads from thevalve to a supply-pipe p, to whichcompressed air may be supplied from any suitable source.

" Below the blank-mold and table B a cylindrical casing H, in which is apin or stem H, projecting slightly above the casing and into theneclvmold, shown at the right hand of Fig. 3. The neck-mold is aperturcdto allow of this projection of the pin thereon, and-the aperture isslightly larger than the pin, so as to leave a narrow annular passageway1' between the pin and the sides of the aperture through the neck-ring.On the stem near the lower end is a valve 8, which is adapted to closethe aperture t throug'lrthe head of the cylindrical casing ll. stem Hextends from the casing H and is connected to the connecting-rod J,which in turn is pivotally connected to the lever J, fulcrurned on therod K hear the base of the machine. This lever is acted uponby a springK, so as to normally hold the pin or stem H in its bottom position andwithdrawn from within the neck-mold or neckring.

, L is an air-supply pipe leading into the The pin oi" chamber withinthe casing I l and this leads to the valve M of any suitableconstruction for eontrollin theadiiiissier'i of the com-- pressed air terefrom. The pipe' L after connecting to the valve M leads likewise tothe main su ly-pipe p. I

On the table B and adjacent to the blankmold is the blowing-mold M, madein sections in the usual manner, each hinged together by means of thehinge-pin M, which extends upward from the table B. These sections areprovided with the usual handles 0 for opening'and closing.

O is a standard beside the l'ilo\'\ 'in'g-mo'l d, having a bifurcatedbracket 1 secured to the upper end. In the outer end of this bracket isslidingly secured the pipe P, which is normally held in its upperposition by means of a spring a between the lower bifurcation of thebracket and the collar 1' on the inc 1.

Q is a lever connected to the co lar o and pivoted in the bracket,adapted to reciprocate the pipe 1. To the upper end of the pipe 1 isattached a supply-pipe ll, having a shut-off valve 11. and acontrol]ing-valve .r thereon. The pipe R likewise leads to the mainair-sup )ly pipe p.

The parts being thus constructed, their operation is as follows: Theoperator first puts the neck-ring ll over the nipple S, which is formedby a slight extension ofthe easing ll above the table, and the spring lwill tightly hold the two sections of the neck-ring togetber. Thebody-blank mold C is then closed and fits tightly upon the upper surfaceof the neck-ring, as shown in Fig. 3. Glass being gathered in anydesired manner is brought to the blank-mold. The head e being turned toone side, the operator.drops the desired quantity of dass into theblank-mold, which will partial y fill it-say to the line a, Fig. 3. Assoon as the gathering-tool is out of the way theoperator grasps thelevert and turns it so that the head a is above the blankmold and thenlowers it upon the blank-mold and at once opens the valve 0, which letscompressed air in through the port or passage m and bears upon the uppersurface of the glass, thus iressmg the glass down in the blank-mold anflcausing the lower end of it to conform to the neck portion thereof andin this case tvherc a bottleis to be. sha ed giving the exteriorformation to the nee The operator having applied his foot to the lever Jand raised the pin ll into the neclemold, as shown in Fig. IS, beforethe glass is dropped into the. blank-mold, when the glass is presseddown to the lower end of the blank-mold the pin will form an initialcavityor blow-opening or indi'int-ation in the lower end of the blank.Any air which may be in the mold below the glass will find a; readyescape through the narrow passage t and 1' between the pin and the sidesof the opening through the neck-ring. The blank will thus be formed withthe neck in the support for the yoke,

part shaped and an indentation therein, and a solid portion of lesserlength conslderablv 'than the bottle and of lesser length than the blankthat is to he formed and from which theibottle is to be blown. In orderto make thei hlqving-blank from the initial blank thus made, it isdesirable or necessary to make a hollow blank from this initial blank,and to do this the operator takes his foot off the lever J,- whiehallows the'pin H to lower and causes the valve s to seat tightly,closing the chamber in the casing ll. Having shut off the valve 0', heopens the valve M, which ad m'its' air into the chamber within thecasing I-I,' which air will pass upward into the indentation or initialblow-o ening in the blank and will expand the blank into the shape shownin dotted lines in Fig. 3. In order to apirise the operator that theblank has been down to full size, I preferably place a small pin T,passing axially through the lower end of the plunger-rod d and havingthe crossingpin T projecting out through the slots T in the side of theplunger-rod d. As soon as the operator sees this pin T rise he will knowthat. the blank is expanded to the size of the blank-mold and the blankis completed. The operator then closes the valve M, re leases his holdof the lever i, which permits the head 0 to rise, opens theblank-mold'C, and gras )ing the levers E of the neck-mold he quirk ylifts the same, together with the blank, and inverts it. The operatorthen slides the neck-mold containing the blank into the open forward endof the yoke Z, which is su )ported on the standard Z and has theguide-flanges Z on its inner face, as clearly shown-m Fig. 3. Theblowing-mold sections M are then closed about the blank and are heldtightly shut, and then the operator grasping the lever Q lowers the pipeP upon the upper face of the opening in the pipe beingopposite theopening in the neck-mold and theopening in the blank. This downwardmovement ofthe pipe P not only makes a tight joint between the pipe andthe neck-n1old, but also moves the neck-mold ti htly down against the up91 end of the bfiiw-mold, which is permitted by the spring and thismakes a tight joint between the arts during the blowing operation. The bank is allowed to remain suspended in the blow-mold for a moment oruntil the blank has elongated,

pref erably, to touch the bottom of theblowmold, and then the operatoropens the valve :r (the valve in being normally open) and the air isadmitted into the blank to'blow the 1 bottle to complete form, as shownin Fig. 3 in dotted lines. I 73 is :1. lug or vertical guide secured tothe rear side of the yoke, beneath which the neckring is slid when itis'put into the yoke, acting to assist in holding the neck-ring inproper position.
